Abstract:
OBJECTIVE To analyze the results of speech-evoked auditory brainstem response(s-ABR)tests in patients with presbycusis and explore the mechanisms of speech coding in these patients.METHODS Thirty patients with presbycusis(presbycusis group),30 elderly individuals with normal hearing(elderly normal group),and 30 young adults with normal hearing(young control group)were recruited.The s-ABR was elicited using a 40 ms duration complex speech stimulus/da/,and the characteristics of s-ABR were analyzed in each group.RESULTS The latencies of waves V and A in the presbycusis group were significantly prolonged compared to both the elderly normal group and the young control group(P<0.05).However,there was no statistically significant difference in the latencies of waves between the elderly normal group and the young control group(P>0.05).The amplitude of wave A and the slope of the V-A complex wave in the presbycusis group were significantly lower than those in the young control group(P<0.05),while no statistically significant differences were observed in the amplitudes of other waves.CONCLUSION The characteristics of s-ABR in patients with presbycusis suggest that these patients have poor synchronization in response to stimulus timing and deficiencies in coding high-frequency and rapidly changing auditory information,which may be one of the mechanisms underlying the decline in speech abilities in patients with presbycusis.
